What most directly causes the exocytosis of Ach in synaptic vesicles? synaptic cleft. When calcium ions enter the synaptic terminal, they cause vesicles containing neurotransmitter molecules to fuse to the plasma membrane of the sending neuron.

What causes the release of acetylcholine from the synaptic vesicles quizlet?
An action potential in the motor neuron causes ACh to be released into the synaptic cleft. Binding of ACh to sarcolemma receptors initiates graded potentials.
What most directly causes synaptic vesicles to release acetylcholine into the synaptic cleft?
What most directly causes synaptic vesicles to release acetylcholine into the synaptic cleft? rationale: Calcium entry causes synaptic vesicles to release acetylcholine into the synaptic cleft.
What causes exocytosis of ACh?
Stimulus-induced acetylcholine (ACh) exocytosis from presynaptic nerve terminals involves two important steps: fusion of ACh loaded vesicles at presynaptic release sites, followed by release into the synaptic cleft. We studied the role of the putative vesicle fusion protein SNAP-25 in this process.
2-Minute Neuroscience: Neurotransmitter Release
What process releases acetylcholine into the synaptic cleft?
The release of acetylcholine occurs when an action potential is relayed and reaches the axon terminus in which depolarization causes voltage-gated calcium channels to open and conduct an influx of calcium, which will allow the vesicles containing acetylcholine for release into the synaptic cleft.
What process releases the neurotransmitter into the synaptic cleft?
exocytosis.
What most directly causes synaptic vesicles?
What most directly causes synaptic vesicles to release acetylcholine into the synaptic cleft? rationale: Calcium entry causes synaptic vesicles to release acetylcholine into the synaptic cleft. Each synaptic vesicle contains thousands of acetylcholine molecules.
2-Minute Neuroscience: Synaptic Transmission
What event directly triggers the release of neurotransmitter shown in A?
What event directly triggers the release of neurotransmitter shown in A? A nerve impulse arrives at the axon terminal triggering the opening of Ca2+ channels, which allows for the diffusion of Ca2+ into the terminal. This in turn leads directly to the release of neurotransmitters by exocytosis.
What is the direct cause of the release of calcium ions from the sarcoplasmic reticulum?
In other words, nervous stimulation leads to depolarization of the sarcolemma (muscle membrane) that triggers calcium ions' release from the sarcoplasmic reticulum.

What triggers exocytosis of synaptic vesicles?
Before exocytosis, neurotransmitter-filled synaptic vesicles are docked at the plasma membrane and primed: exocytosis is triggered by calcium influx.
What causes the release of ACh from the synaptic knob?
A nerve action potential that is initiated in the cell body of a spinal motor neuron propagates out the ventral roots and eventually invades the synaptic terminals of the motor neurons. As a result of the action potential, the chemical transmitter acetylcholine (ACh) is released into the synaptic cleft.
